对于松软粘土中建造浅层隧道时所引起的地面活动进行预测是工程师们面临的主要问题之一。已经用有限元和离心模型研究对隧道变形性能作了测定,并且根据十分明确的有效应力条件下得到的结果提出了一个新的预测地面活动的近似方法。
The prediction of ground activities caused by the construction of shallow tunnels in soft clay is one of the major problems faced by engineers. The deformation properties of the tunnel have been measured using finite element and centrifugal model studies, and a new method for predicting ground motion has been proposed based on the results obtained under well-defined effective stress conditions.
